1 <br /> dewatering wells should be considered for this project so that wetlands are not created in <br /> developable areas. <br /> ' Due to the unknown condition of the groundwater table and in order to evaluate existing <br /> conditions at the Deepe and Turnpike Pit gravel mining sites it was determined that additional <br /> studies should be undertaken. A plan was put together to evaluate existing shale and <br /> groundwater conditions which would include obtaining available data on wells being monitored <br /> on or near the property, construction of 10 to 12 test pits into bedrock and obtaining survey <br /> elevations of existing exposed groundwater. <br /> On July 12, 1996, Western-Mobile personnel dug eleven (11) test pits with a trackhoe at <br /> 1 scattered locations throughout the site. Location of these test pits are shown on Exhibit V-1, <br /> "Contours - Top of Pierre Shale". Each of these test pits were dug to bedrock which is in the <br /> Pierre Shale. The pits were dug by personnel from Westem-Mobile, Inc. on July 12, 1996 and <br /> their locations and groundwater elevations were surveyed by Scott, Cox & Associates on July <br /> 16, 1996. <br /> ' Based upon the water level in the pits after four (4) days, the pits indicated that the depth to <br /> ' groundwater ranges from two to seven feet below the existing ground surface. Two pits were <br /> dry when dug (No. 5 & 11) and were still dry on July 24, 1996 see Table V-1. Five of the pits <br /> (Nos. 2, 3, 4, 6, & 10) appeared to be dry when dug and were filled with a few inches to four <br /> feet of groundwater four days later. <br /> -15- <br />
